Overview

Computer-to-computer backup, also known as inbound backup, is not supported in the version 6.x CrashPlan app. Computer-to-computer backup involves backing up to another computer under the same user. 

When you upgrade to the version 6.x CrashPlan app, computer-to-computer backups stop.

To retain your existing computer-to-computer backup archive, follow these instructions to convert computer-to-computer backups into local folder backups before the upgrade to CrashPlan app version 6.x. This article shows an example of converting a computer-to-computer backup into a backup to an external hard drive. 

Computer-to-computer archives are deleted if not converted
To keep computer-to-computer backups, you must perform these steps before the upgrade to CrashPlan app version 6.x. If you do not complete these steps, your computer-to-computer backup archive is deleted after the upgrade.

Considerations

  • This article uses some specific terms to describe your computer-to-computer backups:
    • Remote computer: The computer receiving your backed-up files
    • Local computer: Your computer that's backing up your files to the remote computer
    • Archive: The collection of files and folders you've backed up
  • At the end of this process, the backup is on an external hard drive. You can apply similar steps to convert the backup to a local backup at another location that you choose. 

Step 1: Locate the backup archive

On the remote computer, find the computer-to-computer backup archive. Look for the folder that matches the local computer's GUID, such as 948212309528060501.

By default, backups from another computer are stored here:

  • Windows:
    • Installed for everyone: C:\ProgramData\CrashPlan\backupArchives
      To view this hidden folder, open a file browser and paste the path in the address bar.
    • Installed per user: C:\Users\<username>\AppData\<Local|Roaming>\CrashPlan\backupArchives
      To view this hidden folder, open a file browser and paste the path in the address bar.
  • Mac: 
    • Installed for everyone: /Library/Application Support/CrashPlan/BackupArchives
    • Installed per user: ~/Library/Application Support/CrashPlan/BackupArchives
  • Linux: /usr/local/var/crashplan/

If you previously changed the default location, find the location that you selected.

Step 2: Copy the backup archive

Copy the archive from the remote computer to an external drive. Use an application like TeraCopy or Rsync, which can verify that files don't become corrupted during copying. Wait for the copy to finish before proceeding.

Copy, don't move
When you transfer your archive, we recommend that you copy the archive instead of moving it. This way, you maintain an intact copy of your archive even if your transfer is interrupted by an event like a power outage.

If your archive is already on an external hard drive connected to the remote computer, you don't have to copy the archive. Simply remove the external hard drive from the remote computer and connect it to your local computer, as described below.

Step 3: Attach the archive on your local computer

  1. Connect the external hard drive to the local computer.
  2. Open the CrashPlan app and go to Destinations > Folders.
  3. Click Select.
  4. Navigate to the archive you want to attach.
    Look for the folder that matches the local computer's ID. For example, 948212309528060501.
  5. Click OK.

Step 4: Start a local folder backup

  1. In the CrashPlan app's Destinations > Folders, select the archive you copied.
  2. Click Start Backup.
    The CrashPlan app begins backing up the file selection to the external drive.

Continue backing up to the external hard drive. Your computer-to-computer backup archive is now converted to a local folder backup. The version 6.x CrashPlan app supports local folder backup, so your archive will be safely retained after the upgrade.
